"expression"
) ]
expression
A C language expression that specifies an IID of a COM interface pointed to by an interface pointer.
Remarks
The iid_is C++ attribute has the same functionality as the iid_is MIDL attribute.
The following code shows the use of iid_is:
// cpp_attr_ref_iid_is.cpp
// compile with: /LD
#include "wtypes.h"
#include "unknwn.h"
[dispinterface, uuid("00000000-0000-0000-0000-000000000001")]
__interface IFireTabCtrl : IDispatch
{
[id(1)] HRESULT CreateInstance([in] REFIID riid,[out, iid_is("riid")]
IUnknown ** ppvObject);
};
[module(name="ATLFIRELib")];
